Title: Apparatus for controlling the number of compressors to be operated
Inventor: HIBINO YOUZOU
IPC: F04B49/02
Filed: 1982-12-24
Abstract: PURPOSE:To avoid superfluous starting and stopping operation, by employing such an arrangement that operation of compressors operated at its full load is switched successively to partial-load operation in case that the discharge pressure of a compressor operated under capacity-controlled mode becomes higher than a value preset for partial-load operation of the compressor. CONSTITUTION:An apparatus 9 for controlling the number of compressors to be operated, which produces a signal for starting or stopping operation of four compressors 1a-1d successively so that the discharge pressure satisfies a set value on the basis of the output signal of a pressure detector 6, a signal for making one compressor operate under capacity-controlled mode, and a signal for operating a required number of compressors at its full load is connected to control boards 3a-3d. Thus, since operation of the compressors operated at its full load is switched successively to partial-load operation in case that the discharge pressure becomes higher than a set pressure, it is enabled to attain a required discharge pressure with minimum energy and to avoid superfluous starting and stopping operation.

IPC: F02D9/02
Filed: 1982-12-24
Abstract: PURPOSE:To restrict an increase in intake resistance or exhaust resistance when the engine is rotated at a high speed, and accelerate an increase in EGR when the engine is rotated at a low speed. CONSTITUTION:The EGR controller 14 is comprised of an ON-OFF valve 16 for opening and closing an inflow port 10 and a throttle valve 18 for opening and closing an exhaust passage 6, which valve 16 is fixed to a valve shaft 20 fitted perpendicularly to the longitudinal direction of the exhaust passage 6, and controls the degree of opening of the inflow port 10. The throttle valve 18 is rotated with the valve shaft 20 as a center to control the degree of opening of the exhaust passage 6. When recirculation of an exhaust gas is required, the valve 16 is rotated to adjust the degree of opening. At this time, since the throttle valve 18 is in parallel with the longitudinal direction of the exhaust passage 6 and is not inclined, the exhaust resistance in the exhaust passage 6 is minimized.

Abstract: PROBLEM TO BE SOLVED: To realize a communication method by which time required for identifying information is reduce and a coordinate reader using it. SOLUTION: In this coordinate reader, a circuit mounted to the circuit substrate 69 of a pen 60 consists of a CR oscillation circuit 69e to which a modulation frequency different by each attribute of a pen such as an ink color, the thickness of a pen tip, etc., is set, an LC oscillation circuit 69c for oscillating a carrier wave for carrying a signal oscillated from the circuit 69e and an FSK circuit 69d for FSK-modulating the oscillation frequency of the circuit 69c by the modulation frequency of the circuit 69e.

Abstract: PURPOSE:To decrease test man-hours and to realize the mechanization of a format by comparing a computer read value with last plant data which is stored previously when plant data is outputted and outputting it on a printer. CONSTITUTION:A comparing means 23 compares the computer read data to be stored in a plant data file 2 with the data which is stored in a read value data storage file 20' at the same point to check the propriety of the data.
